Software teams publish one so customers, sales, and support can see what shipped without asking engineering. A changelog entry usually names the change, explains who it affects, and links to documentation. - [What are release notes, and how do they differ from a changelog?](https://www.changebot.ai/glossary/release-notes/): Release notes are a written summary of what a specific release contains, published when that release ships. A changelog is the running list of those releases over time. Release notes describe one version in depth; a changelog is the archive readers scroll through. - [What is a changelog widget?](https://www.changebot.ai/glossary/changelog-widget/): A changelog widget is an embeddable component that shows recent product updates inside an application, usually behind a bell icon or a "What's new" link. It pulls from the same entries as the hosted changelog page, so one published update appears in both places. - [What is llms.txt?](https://www.changebot.ai/glossary/llms-txt/): llms.txt is a plain-text file at the root of a website that gives large language models a curated, Markdown-formatted map of the site's most useful content. It was proposed by Jeremy Howard in 2024 and is a convention, not a standard: no model is obliged to read it. - [What is MCP?](https://www.changebot.ai/glossary/mcp/): The Model Context Protocol is an open standard, introduced by Anthropic in November 2024, that lets AI assistants connect to external tools and data sources through a common interface. An MCP server exposes tools; an MCP client such as Claude Code or ChatGPT calls them on the user's behalf.
